1 Claim.

This invention relates to windows of the type which embody a counterbalanced slidable sash frame within which is positioned a glazed pivoted sash. This latter sash is preferably tiltable on a horizontal axis to facilitate the washing of tire pane or panes of glass of the pivoted sash. The primary purpose of windows of this character is to permit them to be washed from the inside pivoted sash within the sliding sash and to employ Wholly separate and independent locking devices for locking these sashes against relative pivotal movement. By the present invention, in contradistinction, the means for pivotally mounting the pivoted sash and for locking said sash in closed position are associated with one another in such manner that a part of the pivotal mounting constitutes a portion of the locking means.

This not only greatly simplifies and economizes in manufacturing and installation costs. bu :2-

makes it possible to more satisfactorily coordinate the functions of these devices in a way to insure weather-tight points when the pivoted sash is locked in fully closed position.

In practically carrying out the present in ention we mount, upon the contiguous faces of the adjacent side stiles of the sliding sash frame and pivoted sash frame at each'side of the window, a pair of face abutting metal plates which may be conveniently secured to the respective frames in face abutting relation to one another. The plate which is attached to the pivoted sash is provided with a trunnion while the plate which is secured to the sliding sash is provided with a trunnion seat reinforced at the back of the latter plate by a relatively deep boss, so as to form a fairly long cylindrical bearing for the trunnion. When both sides of the window are thus equipped, the pivoted sash is mounted for smooth and accurate movement from open to closed position, and vice versa, and may be tilted into reversed position for cleaning purposes. The mounting is rugged and will support windows of very considerable weight with thorough efiiciency.

Formed in the plate which is carried by the sliding frame is a locking keeper, preferably in the form of a slot. This is positioned at an appreciable distance from the axis of the pivot and is adapted to receive, when the pivoted sash is in closed position, the nose of a locking latch mounted on the pivoted sash. This locking arrangement may be duplicated at both lateral sides of the window and such an arrangement is preferred for the cooperative relation between the pivot and the latch, coupled with the proper spacing of the slot in the pivot bearing plate, makes it possible to draw the pivoted sash firmly to a seat against the rabbets or weather-stripping commonly employed in windows of this kind so as to make weather-tight joints and eliminate rattling.

Features of the invention, other than those adverted to, will be apparent from the hereinafter detailed'description and claim, when read in conjunction with the accompanying drawing.

The accompanying drawing illustrates different practical embodiments of the invention, but the constructions therein shown are to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is an inside perspective view of a window frame and sash assembly embodying the present invention.

Figure 2 is a fragmental perspective showing sliding and pivoted sash portions associated according to the present invention and locked in closed position.

Figure 3 is a like view showing the pivoted sash unlocked and tilted with respect to the sliding sash.

Figure 4 is a section on the line 4-4 of Figure 2.

Figure 5 shows a modified form of construction adapted for use where the inner face of the sliding sash is flush with the inner face of the pivoted sash.

By reference first to Figure 1 of the drawing, it will be noted that l indicates the usual millwork window frame having double hung upper and lower sliding sashes 2 and 3, respectively, within which are mounted the pivoted sashes 4 and 5, respectively. The upper and lower sashes are counterbalanced for sliding movement and the sliding sashes Z and 3 may be locked together in the usual way by a suitable window catch.

In practice the pivoted sashes are usually rabbeted into the sliding sashes so as to produce weather-proof joints, the rabbets being reversed in the lower and upper portions of the respective sashes to permit of the pivotal movement desired.

We have not considered it necessary to show the details of this rabbeting nor of weather-stripping which may be employed in connection therewith. These features may be conventional and are well understood by those skilled in the art.

In Figures 2, 3 and 4, 6 indicates the left hand side stile of one of the sliding sashes, as viewed in Figure 1, and i indicates the adjacent side stile of the cooperating pivoted sash, glazed at 8. At approximately midway of the height of the side stiles, there is positioned two plates 9 and H] in face abutting relation. The plate 9 is secured by means of screws H, or otherwise, to the inner face of the side stile 6, while the plate I0 is similarly secured to the opposing face of the side stile l of the pivoted sash. Plate ii] is provided with a trunnion i2 extending outwardly therefrom and adapted to project into a hole IS in the plate 9. Back of this latter plate in the region of the hole is a boss I l (see Fig. 4) and the hole extends through the boss so as to give a long bearing for the pivot and thus minimize wear. The structure described is duplicated at both sides of the window and thus each pivoted sash is supported for pivotal movement within its associated sliding sash frame.

In the structure of Figs. 2-4, the pivoted sash is shown as of less thickness than the sliding sash and consequently the plate 9 of the latter may be made to project beyond the inner face of the pivoted sash sufiiciently to permit of the formation directly within this plate of an upright slot i5. Back of the slot the wood or metal of the side stile 9 may be cut away, as shown at I6 in Figure 4, so as to receive through said slot the nose I! of a locking latch iii. The slot I5 is thus adapted to function as the keeper of the latch.

This locking latch is secured by a pivot 19 to the inner fac of the pivoted sash and is provided with a finger piece 2!] by means of which the latch may be rotated about the pivot l9 to engage or disengage its nose H with the slot l5 and thus lock or unlock the pivoted sash. Fig. 2 shows the parts in locked position with a tail 2| formed on the finger piece and bearing against the inner edge of the side stile l to limit the movement of the latch in looking direction. Fig. 3 shows the locking latch rotated into fully unlocked position. Here the tail 2! also engages with the edge of the side stile to limit the movement of the latch in the unlocking direction.

It will be noted that the nose of the latch is chamfered along its edges. This is to permit a wedging action between the forward edge of the slot and the nose of the latch as the latch is forced into locking position in order that the pivoted sash may be drawn into tight interifitting relation with the rabbets of the sliding sash to insure weather-tight joints between them.

In practice the plates 9 and in are preferably made fairly heavy and sufficiently long so that the latch will be positioned at some little distance from the axis of pivotal movement of the pivoted sash. In this way the lock is made eflicient in securing the pivoted sash in closed position.

In Figs. 2, 3 and 4, the plate 9 is extended for its full height a distance sufiicient to receive the slot l5 for here the pivoted sash is recessed with respect to the sliding sash. However, in such installations as shown in Fig. 5 where the inner faces of both sashes are flush, then the plate 9a of the sliding sash (corresponding to the plate 9) is cut off flush with the inner face of said sash except in the vicinity of the slot I5 where it is extended inwardly as shown at 91) to receive such slot. Except for these differences, the structures of Figs. 2 and 5 are the same.

The structures illustrated in Figs. 2-5 are duplicated at opposite sides of the window except that the latch need not be duplicated unless desired, but the duplication of the latch is preferred.

In each instance, the locking latch may be mounted in face abutting relation to the inner face of the side stile of the pivoted sash, although it is preferably spaced slightly therefrom by a washer 22, so that the finish on the sash is not marred when the latch is rotated.

The window hardware hereinbefore described is simple in construction, but is so constituted that it may be used on practically every make of combination hung and pivoted window, i. e., it is adapted for general application. For this reason we have not illustrated in detail the rabbet arrangements of any particular window nor weather-stripping which may be associated in practice with this structure. Those skilled in the art can readily supply the same, which will in practice depend upon the particular window with which the structure is associated.

Figures 2, 3 and 4 show the sashes as made from wood while Figure 5 shows metallic window construction. This is merely for illustrativepurposes. The invention may be associated with sashes made from any material.

The foregoing detailed description sets forth the invention in its preferred practical form, but the invention is to be understood as fully commensurate with the appended claim.

. Having thusfully described the invention, what we claim as new and desire to secure by Letters Patent is:

Looking means for a combination hung and hinged window of the type wherein a glazed pivoted sash is mounted on horizontal pivots within a sliding sash; comprising a pivoted locking latch mounted on the inner face of a side stile of the pivoted sash in cooperative relation to a locking opening carried by the sliding sash, said latch having a nose to be moved into and out of said opening as the latch is pivotably moved when the pivoted sash is in closed position, and an operating finger piece on the locking latch positioned to engage with the glazed edge of said side stile of the pivoted sash when the latch is in both locking and unlocking positions.
